View the official Windows Driver Kit DDI referenceNo description available.
This routine inserts an object in a Silo.
Silo [in]A pointer to a silo. This parameter is required and it cannot be NULL.
ContextSlot [in]A slot allocated by the PsAllocSiloContextSlot routine.
NewSiloContext [in]A pointer to the object created by the PsCreateSiloContext routine. The object must be created using the same silo pointer as the one specified in this routine. This parameter is required and it cannot be NULL.
OldSiloContext [optional]A pointer to a caller-allocated variable that receives the address of the existing object. This parameter is optional and can be NULL. The address that the parameter receives can be NULL.
The following NT status codes are returned.
| Return code | Description |
|---|---|
| STATUS_INSUFFICIENT_RESOURCES | There are no resources in the system to perform the insert. This is an error code. |
| STATUS_NOT_SUPPORTED | The slot is read-only and it cannot be modified. This is an error code. |
| STATUS_SUCCESS | The operation completed successfully. |
A successful call to PsReplaceSiloContext increments the reference count on NewSiloContext. If PsReplaceSiloContext fails, the reference count remains unchanged. In either case, the caller of PsReplaceSiloContext must call PsDereferenceSiloContext to decrement the PsReplaceSiloContext object. If PsReplaceSiloContext fails and if the OldSiloContext parameter is not NULL and does not point to NULL then NULL is a referenced pointer. After the routine completes, the caller must call PsDereferenceSiloContext to decrement the object that the NULL parameter points to.
